Question

Расстояние между поселками 30 км лыжник прошел за 3 часа на обратном пути он уменьшил скорость на 4 км час сколько времени он потратил туда и обратно???????????

Answer 1

1) 30:3=10(км/час) скорость лыжника в одну сторону                                          2) 10-4=6(км/час) скорость лыжника на обратном пути                                       3) 30:6=5(часов) времени потратил на обратный путь                                        4) 3+5=8(часов времени потратил на всю дорогу)                                                 Ответ: Лыжник потратил на дорогу туда и обратно 8часов времени 

Answer 2

1) 30:3 = 10(км/ч) скорость за 3 часа
2)10-4=6(км/ч) скорость обратно
3) 30:6= 5 (ч)обратно
4) 3+5=8 (ч) всего потрачено времени

Answer 3

Calculation of Time Spent on the Round Trip

To calculate the time spent on the round trip, we need to consider the distance between the villages and the speed of the skier.

Given: - Distance between the villages: 30 km - Time taken for the forward journey: 3 hours - Speed reduction on the return journey: 4 km/h

To find the time spent on the return journey, we can calculate the speed of the skier on the return journey by subtracting 4 km/h from the speed on the forward journey.

Let's calculate the time spent on the return journey:

Speed on the forward journey: We are given the distance (30 km) and the time taken (3 hours) for the forward journey. We can calculate the speed using the formula: speed = distance / time.

Speed on the return journey: To find the speed on the return journey, we subtract 4 km/h from the speed on the forward journey.

Time spent on the return journey: We can calculate the time spent on the return journey using the formula: time = distance / speed.

Now let's calculate the time spent on the round trip step by step:

1. Calculate the speed on the forward journey: - Distance: 30 km - Time: 3 hours - Speed = distance / time = 30 km / 3 hours = 10 km/h

2. Calculate the speed on the return journey: - Speed on the forward journey: 10 km/h - Speed reduction: 4 km/h - Speed on the return journey = Speed on the forward journey - Speed reduction = 10 km/h - 4 km/h = 6 km/h

3. Calculate the time spent on the return journey: - Distance: 30 km - Speed on the return journey: 6 km/h - Time = distance / speed = 30 km / 6 km/h = 5 hours

Therefore, the skier spent 5 hours on the return journey.

To find the total time spent on the round trip, we add the time spent on the forward journey (3 hours) and the time spent on the return journey (5 hours):

Total time spent = Time spent on the forward journey + Time spent on the return journey = 3 hours + 5 hours = 8 hours.

So, the skier spent a total of 8 hours on the round trip.
